Top 10 Things NOT To Do While Coparenting

Most coparenting damage is not done by big decisions. It is done by small habits that feel reasonable in the moment, which is what makes them hard to notice in yourself.

This is the quick reference list: ten things not to do, and what to do instead. For the deeper version of the worst five, with what each one actually costs, see the mistakes that wreck a coparenting relationship.

1. Don’t Badmouth Your Coparent

Speaking negatively about your coparent in front of your children can cause emotional distress and confusion. It’s important to keep your personal feelings separate from your parenting responsibilities.

• Why not: children hear half of themselves in the description. Criticising their other parent is criticising where they came from, and they take it personally even when it is accurate.
• Instead: neutral or nothing. This includes the version delivered by tone — children hear the sigh at the caller ID. Save the real feelings for a friend or a therapist.

2. Don’t Use Your Children as Messengers

Asking your children to relay messages to your coparent puts them in an uncomfortable position and can lead to miscommunication.

• Why not: your child now owns the reaction. “Mum says you need to pay for the trip” makes a nine-year-old responsible for whatever comes next.
• Instead: send it yourself, every time, through the app or email. This single habit removes the most common version of putting a child in the middle. A coparenting app makes it the path of least resistance.

3. Don’t Make Your Children Choose Sides

Forcing your children to choose between parents can cause significant emotional harm and strain their relationship with both parents.

• Why not: it rarely looks like asking outright. It looks like a pause after they mention a good weekend, or a question about whether they had fun that is not really a question.
• Instead: say out loud that they are allowed to love both parents. Children in this position assume otherwise and will not raise it themselves.

4. Don’t Ignore Boundaries

A boundary your coparent ignores is annoying. A boundary you stop enforcing is worse, because it teaches what works.

• Why not: a limit that moves under pressure teaches that pressure works, which costs more than the original inconvenience.
• Instead: state it once, without the reasoning, then keep it on the day it is inconvenient. The reasoning is the part that gets argued with.

5. Don’t Fight in Front of Your Children

Arguing in front of your children can create a stressful environment and negatively impact their emotional well-being.

• Why not: sustained hostility between parents tracks worse outcomes for children more closely than the separation itself does.
• Instead: nothing gets resolved at a handover. Put it in writing, decline to engage at the exchange, and take the recurring ones to a mediator.

6. Don’t Withhold Information

Failing to share important information about your children’s health, education, or activities can lead to misunderstandings and mistrust. It can also effectively put your kids in the middle by forcing them to be the conduit of basic information about their care.

• Why not: the information reaches the other parent anyway, through your child, who should not be the one carrying it.
• Instead: send a short weekly news report. School, health, friends, anything upcoming. Also get yourself on the school’s contact list directly, so neither of you depends on the other forwarding things.

7. Don’t Make Assumptions

Assuming the worst about your coparent’s intentions can lead to unnecessary conflicts and misunderstandings.

• Why not: a late pickup reads as contempt when you are braced for contempt. Sometimes it is traffic.
• Instead: ask the flat question before writing the angry message. “Were you held up?” costs nothing and is right often enough to be worth it.

8. Don’t Use Your Children as Spies

Asking your children for information about your coparent’s personal life is invasive and unfair to them.

• Why not: children work out quickly which answers get a reaction, and start editing. That is how you stop hearing the truth about either house.
• Instead: no questions about the other parent’s life, no follow-ups on anything they volunteer about it. If they raise something genuinely concerning, hear it, write it down privately, and do not perform a reaction.

9. Don’t Ignore the Legal Agreement

Failing to adhere to the custody or visitation agreement can lead to legal consequences and increased tensions.

• Why not: breaching because they breached first hands them the stronger position. The court asks about your breach, not what prompted it.
• Instead: keep your side, document theirs, and get the order amended if it no longer fits your lives.

10. Don’t Neglect Self-Care

Ignoring your own well-being can lead to burnout and negatively affect your parenting.

• Why not: tired people misread messages and lose arguments they were winning.
• Instead: protect sleep specifically, keep one friendship outside the conflict, and put something in your week that has nothing to do with any of it.

If You Recognise Yourself in Some of These

Most people do. Several of them are things you do without deciding to, usually while tired and usually after a message that made your chest tight.

Pick one. The messenger habit is the highest-value place to start, because it is the most common and the easiest to stop: every message that could go through your child goes through the app or email instead.
